The 2016 Democratic National Committee email leak is a collection of Democratic National Committee (DNC) emails leaked to and subsequently published by WikiLeaks on July 22, 2016. The collection included 19,252 emails and 8,034 attachments from the DNC, the governing body of the United States' Democratic Party.

The leak includes emails from seven key DNC staff members, and date from January 2015 to May 2016. The leak prompted the resignation of DNC chair Debbie Wasserman Schultz before the Democratic National Convention. After the convention, DNC CEO Amy Dacey, CFO Brad Marshall, and Communications Director Luis Miranda also resigned in the wake of the controversy.
